Definitions
- the invention relates to a device for performing the method for electro-slag or electro-gas welding of metal sheets, in which powdered filler material is introduced into the welding gap.
- the feed nozzles for the metal powder must be directed exactly in the middle of the wire electrode pairs and they must open out just above the slag bath surface. Otherwise, short-circuit bridges made of metal powder can form between the sheet edge and the wire electrodes. The nozzles only meet this requirement for the accuracy of the metal powder feed when the settings are carefully made. In addition, this variant of the metal powder supply is limited to two pairs of wire electrodes.
- the object of the invention is to simplify the operation of the welding device in a conventional device and to avoid the disruptive influence of the magnetic fields emanating from the electrodes on the conveyance of the metal powder.
- pairs of current probes have a magnetic shield to which the tubes are fastened in the field-poor space.
- U-shaped stamped transformer sheets are used for magnetic shielding, which, coated on one side, are stacked into rails, in the groove of which the pairs of current probes are guided, the feed lines for the metal powder being outside on the web part of the U- Profiles are attached.
- These laminated U-rails conduct the magnetic field outwards preferably over the free ends of the U-profile and a space with little field is created on the back of the profile in which the feed pipes for the metal powder are arranged.
- the feed tubes open out of the current probes just below the wire electrode outlet and can spray the metal powder onto the wire electrodes.
- Three wire electrode pairs 3 are required for welding thicker sheets 5. Each pair is equipped with a feed tube 11 for metal powder as filler material, which is connected to the current probes for the electrodes to form a unit. In order to create a field-poor space for the tubes 11. U-shaped stamped transformer sheets A are stacked to form laminated rails with a U-profile, in which the current proboscises run with the wire electrodes, the magnetic fields emerging from the free edges of the U-profile. Magnetic shielding is not required for the lines 10 for the non-magnetic welding powder.
